Thundercracker was the designation for a series of drone units used in the Decepticon occupation of Earth. Dreadwing and Starscream led a group of Thundercrackers in the annihilation of the NATO nuclear fleet. The drones were skilled enough to take out submarines with their guns whilst still in high-speed flight.
